Origami Menger Sponges

1. Begin with a cube.
2. Shrink the cube to 1 / 3 of its original size and make 20 copies of it.
3. Place the copies so they will form a new cube of the same size as the original one but lacking the centerparts, (next image).
4. Repeat the process from step 2 for each of the remaining smaller cubes.
After an infinite number of iterations, a Menger sponge will remain.

from Wikipedia

The Menger Sponge is a fractal particularly appealing to modular origamists, for two reasons: it can be made out of Sonobe modules (the very first “brick” that every origamist learns), and given its fractal nature, it can be expanded forever and ever. What follows is a list of origami websites on this fascinating structure: Continue reading Origami Menger Sponges

Forecoming gadgets: round, interactive and shaky

When I first wrote an article on Hitachi’s waterscape, I defined the device as a “study for new, more intuitive ways of accessing data in electronic devices”, also pointing out that the technology could also be useful for playing interactive videogames. Now, it seems that other major companies Continue reading Forecoming gadgets: round, interactive and shaky

Origami Wreaths and Rings

a book by David Petty

In these pages you will find over 100 inventive variations around a circular theme using modular origami

If I were to describe this book in as few words as possible, I would choose these: easy, modular, organic origami. Easy, because the folding instructions are very clear and each of the pieces can be made in a few minutes by people with none to very little knowledge in origami; modular, because you create the models by assembling several small identical units together; and organic, because the result is a whole which looks much more complex than the sum of its parts: actually, many of the spiky stars and rings remind me of living sea stars and urchins. I came to this book after having seen several models a friend of mine had done, and I recommend it to anyone interested in any of the key themes mentioned above, as it will be a pleasing and rewarding discovery.

Update: I just found out that the author has made available several models with instructions here.
